The secret ingredient of ChatGPT is human advice

Published Wed, 13 Nov 2024 14:11:19 GMT

In November 2022, the company behind Facebook released a chatbot called Galactica. After a torrent of complaints that the bot made up historical events and spewed other nonsense, Meta removed it from the internet.Two weeks later, the San Francisco startup OpenAI released a chatbot called ChatGPT. It was a worldwide sensation.Both bots were powered by the same fundamental technology. But unlike Meta, OpenAI had sharpened its bot using a technique that was just beginning to change the way artificial intelligence is built.In the months leading up to the release of ChatGPT, the company hired hundreds of people to use an early version and provide precise suggestions that could help hone the bot’s skills. Like an army of tutors guiding a grade school student, they showed the bot how to respond to particular questions, rated its responses and corrected its mistakes. By analyzing those suggestions, ChatGPT learned to be a better chatbot.The technique, “reinforcement learning from human feed...

For consumers, the cost of a used car in Denver not aging well

Published Wed, 13 Nov 2024 14:11:19 GMT

What it cost to buy a 3-year-old used vehicle back in 2019 would today only pay for something that is 7 years old in Denver, according to a study from iSeeCars.com.That trend is national, and it reflects both inflation as well as a decrease in new car production between 2020 and 2022 because of the pandemic. The big run-up explains, in part, why consumers are under such financial pressure, not only when it comes to where they live, but also what they drive.The auto website looked at over 21 million used car sales to determine the average price of a 3-year-old model in 2019 and what that same model would cost to buy in Denver and other cities.Across all models, the average cost of a 3-year-old car in Denver in 2019 was $24,449. But by 2023, it was $36,146, a gain of 47.8%. Converted to years, what was spent on a 3-year-old car in 2019 will only buy a car that is 7 years old today on average.Some models go above that. A 3-year-old Chevrolet Spark cost an average of $10,105 in 2019. Bu...

Wilcox zooms past Mountain View to open league play with 45-14 win

Published Wed, 13 Nov 2024 14:11:19 GMT

SANTA CLARA — Mountain View opened Friday’s game against Wilcox exactly how head coach Tim Lugo wanted.The Spartans used a trick play to get the ball into the hands of receiver Lex Silver for a 74-yard touchdown.Not only did the score put Mountain View on the board first, but Lugo also felt it gave his team a needed confidence boost to start what he expected to be a dogfight.The Spartans’ edge didn’t last long. Wilcox answered with a score of its own less than a minute later and ended up being the aggressors the rest of the night, resulting in a 45-14 beatdown of Mountain View to open league play.“We played good defense after… they scored,” Wilcox coach Paul Rosa said. “We settled down and got the ball back quickly after that.”Senior quarterback Tyson Bonilla carved up Mountain View’s defense throughout the first half and start of the third quarter. His ability to change his speed and direction without warning gave the Spartans trouble...

Clendaniel: A parting wish for readers as I retire from the editorial page

Published Wed, 13 Nov 2024 14:11:19 GMT

Time really does fly when you’re having fun.In 1985, I walked into The Mercury News for the first time and couldn’t believe my good fortune to be working at a newspaper in one of the most beautiful and intriguing regions in the world. Except for a five-year stint from 1997-2002 as a stay-at-home dad and editor for Forbes ASAP magazine, I’ve been here ever since.But on Friday, after writing about 2,000 editorials and columns and editing more than 25,000 letters to the editor, I retired as The Mercury News editorial page editor and a member of the East Bay Times editorial board.As a lifelong newspaper junkie, I know I’m going to miss the job — a lot. For the last two decades of my career, a newspaper paid me to have an opinion. How cool is that? I, in turn, did my best to fulfill our opinion-page mission of advancing debate on key issues facing our readers.Who else gets to identify the leading topic of the day and then call the best experts to discuss it?...

Mahan: Time for the blame game on homelessness to end

Published Wed, 13 Nov 2024 14:11:19 GMT

After the 1906 earthquake, San Francisco quickly constructed over 5,600 cottages to house those made homeless by the catastrophe. City leaders didn’t say “a cottage isn’t good enough” or “someone else is to blame” or, worse, “this is unsolvable.”They recognized that in an emergency, you take emergency action — such as building simple, decent shelters for everyone affected.They placed these cottages on public land and then, as the emergency ebbed, residents were allowed to relocate them. They were the first homes for thousands of families. You can still find them across the region.We’ve seen elected officials offer excuse after excuse for our state’s failure to adequately address homelessness. We’ve blamed the courts, we’ve blamed the cost of building housing, and we’ve blamed the homeless.It’s time for the blame game to end. It’s time California created safe, decent and affordably constructed shelter for everyone — and then required those sleeping outdoors to use it. It’...

Published Wed, 13 Nov 2024 14:11:19 GMT

GUIDONIA MONTECELIO, Italy (AP) — Max Homa had already taken his hat off and was walking toward playing partner Brian Harman for a celebratory hug before his chip for eagle rolled in on the reachable par-4 16th.Nearly 28 hours into the Ryder Cup, the two rookies clinched the Americans’ first full point by beating Shane Lowry and Sepp Straka 4 and 2 in morning foursomes Saturday at Marco Simone.“We needed something to go our way,” Homa said. “Somebody had to start a spark, so I’m just glad it was us.”The only problem was that was the only point the U.S. earned in the session, leaving Europe extending its advantage to 9½ to 2½.“We obviously are in a big hole but we have the right guys to dig ourselves out of it,” Homa said.Homa went 4-0 in his first team experience at the Presidents Cup last year and also earned a half point with Wyndham Clark in afternoon fourballs on Friday against Robert MacIntyre and Justin Rose. But that felt like a loss after Homa missed a putt on 18 to win it —...

El hombre acusado de matar a tiros a Tupac Shakur en 1996 está hace mucho tiempo ubicado en la escena del crimen. Esto es lo que sabemos sobre él

Published Wed, 13 Nov 2024 14:11:19 GMT

(CNN) — Ya en 1998, Duane Keith Davis le dijo a un canal de cable que era el pasajero del asiento delantero de un automóvil desde el cual un compañero de viaje disparó los tiros que mataron a Tupac Shakur.En 2009, Davis, conocido como “Keffe D”, confesó a la policía su papel en el caso, dijo a CNN un exdetective que investigó el tiroteo, pero las autoridades no pudieron utilizar la información en ese momento.Y luego, después de lo que la policía dice que fue un nuevo impulso a la investigación, Davis, de 60 años, fue arrestado en Las Vegas el viernes, y un jurado investigador lo acusó por asesinato con uso de un arma letal. El arresto se produce unos 27 años después de que el rapero recibiera un disparo cuando salía de una pelea de box en el Strip de Las Vegas.El tiroteo del 7 de septiembre de 1996 fue un ataque en represalia contra la estrella de 25 años, dijo la policía el viernes. Las autoridades alegan que Davis planeó y orquestó el tiroteo en cuestión de horas...
